JLPT Kanji flashcards for JLPT N5 and N4 for Kindle

If you are interested, please find the kanji required for the Japanese Language Proficiency Test (JLPT) levels N5 and N4 in Mobi format for Kindle here and here. I prepared them for myself to be able to practice while on the go, but decided to share the files. Comments are welcome but the files come as they are.
I’ll be preparing vocabulary and grammar lists next, revisit from time to time to check for updates.
